一、南告水电站调压井水工模型试验 (一)基本情况与试验目的 南告水电站系引水式电站,位于广东省陆丰县螺河上支流南告水,电站总装机容量为3×15,000千瓦。 电站引水管直径3米,总长约4公里,调压井前管长约3,121米,井后接高压钢管长890米。调压井型式初设计时为上室附有溢流口的双室式调压井;由于地质条件差,技施设计阶段决定取消下室,保留上室附有溢流口及汇流孔,加大竖井直径,并在井内布置事故闸门,属于上室附有溢流口的简单式调压井。见图1。
I. Model Test of Surge Tank Surgery in Nankao Hydropower Station (I) Basic Conditions and Test Purposes Nanyan Hydropower Station Diversion Power Station is located in Nanxuanshui, the upper reaches of the Lo River in Lufeng County, Guangdong Province with a total installed capacity of 3 × 15,000 kW. Power station diversion pipe diameter of 3 meters, a total length of about 4 km, the surge before the tube length of about 3,121 meters, followed by high-pressure steel pipe 890 meters long. Surge chamber type design at the beginning of the design for the upper chamber with overflow port dual-chamber surge tank; due to poor geological conditions, technical design phase decided to cancel the next room to retain the room with an overflow port and the convergence hole, plus Large shaft diameter, and layout of the accident gate in the well, belonging to the upper chamber with a simple surge port regulator. see picture 1.
